'Horn' in the Bible

I considered the horns, and behold, there came up among them another, a little horn, before which three of the first horns were plucked up by the roots; and behold, in this horn were eyes like the eyes of a man, and a mouth speaking great things.

I beheld therefore, because of the voice of the great words that the horn spoke; I beheld till the beast was slain, and its body destroyed, and it was given up to be burned with fire.

and concerning the ten horns that were in its head, and the other that came up, and before which three fell: even that horn that had eyes, and a mouth speaking great things, and whose look was more imposing than its fellows.

I beheld, and that horn made war with the saints, and prevailed over them;

And as I was considering, behold, a he-goat came from the west over the face of the whole earth, and touched not the ground: and the goat had a notable horn between his eyes.

And the he-goat became exceeding great; but when he was become strong, the great horn was broken; and in its stead came up four notable ones toward the four winds of the heavens.

And out of one of them came forth a little horn, which became exceeding great, toward the south, and toward the east, and toward the beauty of the earth.

And the rough goat is the king of Greece; and the great horn that was between his eyes is the first king.
